Capistrano无法部署到远程服务器
解
解决方案是将以下内容添加到production.rb的顶部：
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path. require "rvm/capistrano" # Load RVM's capistrano plugin. set :rvm_ruby_string, '1.9.2@rails31dataserver' # Or whatever env you want it to run in. set :rvm_bin_path, '/usr/local/rvm/bin' 我之前缺少的部分是set :rvm_bin_path, '/usr/local/rvm/bin'因为我之前从未在Capistrano部署中使用过该配置设置，而且我做了一些。 哦，好吧，一天都工作。 信用转到irc.freenode.net上#rvm频道的tonyflint！

- 我正在运行RVM的系统安装
- 我正在通过Capistrano部署
我目前傻眼了。 基本上发生的事情是我正在尝试通过Capistrano进行部署，而且它很难，很难。 这是我的deploy.rb和production.rb文件的pastie（我正在做一个多阶段环境并省略staging.rb文件，因为它工作正常）。 http://pastie.org/2523675
以下是cap production deploy:setup的输出cap production deploy:setup ：
$ cap production deploy:setup * executing `production' triggering start callbacks for `deploy:setup' * executing `multistage:ensure' * executing `deploy:setup' * executing "sudo -p 'sudo password: ' mkdir -p /var/www/html/dataserver /var/www/html/dataserver/releases /var/www/html/dataserver/shared /var/www/html/dataserver/shared/system /var/www/html/dataserver/shared/log /var/www/html/dataserver/shared/pids" servers: ["omitted"] Password: [omitted] executing command *** [err :: omitted] sudo *** [err :: omitted] : *** [err :: omitted] sorry, you must have a tty to run sudo *** [err :: omitted] command finished in 60ms failed: "sh -c 'sudo -p '\\''sudo password: '\\'' mkdir -p /var/www/html/dataserver /var/www/html/dataserver/releases /var/www/html/dataserver/shared /var/www/html/dataserver/shared/system /var/www/html/dataserver/shared/log /var/www/html/dataserver/shared/pids'" on omitted
现在，我知道为什么会这样。 我正在远程尝试使用sudo，这是一个安全禁忌。 所以，这意味着我需要使用default_run_options[:pty] = true 。 所以我取消注释它并运行cap production deploy:setup再次cap production deploy:setup并且所有运行都很好和花花公子。 部署的目录结构获取设置和所有内容。 真棒。 现在我尝试运行cap production deploy ，这是输出：

因此看来无论它加载什么环境都看不到rake 。 要查看我创建部署任务的路径中加载的内容，请输出以下内容：
$ cap production test_path * executing `production' triggering start callbacks for `test_path' * executing `multistage:ensure' * executing `test_path' * executing "echo $PATH" servers: ["omitted"] Password: [omitted] executing command ** [out :: omitted] /usr/local/bin:/bin:/usr/bin command finished in 11ms * executing "echo $rvm_path" servers: ["omitted"] [omitted] executing command ** [out :: omitted] command finished in 5ms
现在你会注意到路径绝对不正确。 对于正在建立会话的用户，应该是以下内容：
/usr/local/rvm/gems/ruby-1.9.2-p290@rails31dataserver/bin:/usr/local/rvm/gems/ruby-1.9.2-p290@global/bin:/usr/local/rvm/rubies/ruby-1.9.2-p290/bin:/usr/local/rvm/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/lpeabody/bin
而且，我知道为什么这不起作用。 这是因为我正在运行default_run_options[:pty] = true我的环境正在加载，至少这是我目前的理论。 所以，毕竟，我得出结论 – 我需要以某种方式加载我的环境，以便rake可以在不启用远程sudo的情况下运行。
现在，我知道我不是唯一需要这样做的人，所以任何指针或提示都将非常感激。 我已经把我的大脑放在了8个小时的大部分时间里，我需要尽快部署这个应用程序。
解决方案是将以下内容添加到production.rb的顶部：
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path. require "rvm/capistrano" # Load RVM's capistrano plugin. set :rvm_ruby_string, '1.9.2@rails31dataserver' # Or whatever env you want it to run in. set :rvm_bin_path, '/usr/local/rvm/bin'
我之前缺少的部分是set :rvm_bin_path, '/usr/local/rvm/bin'因为我之前从未在Capistrano部署中使用过该配置设置，而且我做了一些。 哦，好吧，一天都工作。 信用转到irc.freenode.net上#rvm频道的tonyflint！
确保你运行：
gem install rvm-capistrano
在你放之前
require "rvm/capistrano" in your "deploy.rb"
在我这样做之后，它有效。
在capfile中尝试一些事情（这些是用于系统范围的RVM安装，不适用于每用户安装。）
require "rvm/capistrano" set :rvm_bin_path, "/usr/local/rvm/bin" $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
在我的情况下，添加
default_run_options[:pty] = true
解决了这个问题。
